MBA“运营管理”教学面临的困惑与思考     

张聪群  李宏宇 《宁波大学学报(教育科学版)》2015,(1):68-72

“运营管理”是MBA的核心课程之一。MBA“运营管理”教学面临研究对象的变化与教材内容体系的混乱、MBA 学员背景的差异与需求的多元化、网络信息技术对企业运营系统与运营活动的影响等困惑,直接影响MBA“运营管理”课程的教学效果。MBA“运营管理”课程可以从课程内容拆分、制造企业运营与服务企业运营分离、学员根据工作需要选修等措施进行尝试性的改革与探索。  相似文献

高职院校“生命化”主题实践活动的内容研究     

张和新 《长江工程职业技术学院学报》2015,(1):46-48

高职院校生命化主题实践活动的内容,可以归结为生命、生活、生态——"三生"内容。具体来讲,又可以细化为认识、处理四种关系:人与自身的关系,人与他人的关系,人与自然的关系,人与宇宙的关系。这其中体现生命化教育内容的三点特征:一是直面生命——以生命为教育的起点,二是在生命中——尊重生命的特性,三是为了生命——享受美好的生活和幸福人生。  相似文献

Determination of Biological Variance and Validation of a Fluorometric Assay for Measurement of α-l-Iduronidase Activity in Dried Blood Spots Samples: The First Experience in Iran     

Mohammad Abdi  Mohammad Said Hakhamaneshi  Mohammad Reza Alaei  Namam-Ali Azadi  Rahim Vakili  Daniel Zamanfar  Mohammad Taghikhani  Shohreh Khatami 《Indian journal of clinical biochemistry : IJCB》2015,30(3):318-322

Methods for assaying lysosomal diseases in dried blood samples are very useful today due to its several advantages related to the stability of samples, its transportation, handled and analysis, and its potential use for newborn screening compared to traditional methods in leucocytes samples. For this reason, it is important to validate these assays before being used in routine laboratory. Because of different in biological markers based on ethnicity, we aimed this study to validation a DBS-based fluorometric assay for measurement of α-l-Iduronidase activity for diagnosis of MPS I patients in Iran. DBS samples were collected from 15 MPS I patients and 60 healthy age matched subjects. Diagnostic value, biological variance and α-l-Iduronidase activity were determined. DBS α-l-Iduronidase activity was significantly higher in male subjects than in female group. Using a cut-off level of 1.08 µmol/spot 20 h, sensitivity and specificity were 100 and 98 %. The linearity of test was proved and we showed that within-run and between run precision were 5.6 and 14.66 %. Measurement of α-l-Iduronidase activity in DBS samples is an accurate test for diagnosis of MPS I and because of its rapid shipping and simplicity to keeping, DBS-based enzyme activity could be considered as a useful diagnostic tool in this disease.  相似文献   

Girls’ active identities: navigating othering discourses of femininity,bodies and physical education     

Joanne Hill 《Gender and education》2015,27(6):666-684

Within physical education and sport, girls must navigate discourses of valued athletic and gendered bodies that marginalise or ‘other’ non-normative performances through systems of surveillance and punishment. The purpose of this paper is to share girls’ perspectives on how these discourses affected their gender performances and activity engagement. Students aged 13–14 in one ethnically diverse UK secondary school were invited to create a photo diary of the physical activities they engaged in. Photo-elicitation interviews in small groups followed. The girls positioned themselves as physically active but had to carefully manage their activity choices and gender performances in a single-sex physical education environment that regulated deviation from the fit, slender, girly-girl. Although the girls demonstrate the difficulty of resisting, they indicate moments of positioning themselves against norms that suggest the possibilities of shifting gendering processes. The paper points out the importance of listening to ‘other’ girls’ narratives in building positive physical education engagements.  相似文献

目的：探讨应用智能手机运动软件监控体力活动对日常体力活动的影响及其内在机理。方法：选取广州市年龄35~45岁之间的白领38名作为研究对象，实验前、后受试者填写《国际体力活动问卷长卷》问卷，实验中受试者采用动动健康软件管理目标体力活动量，并将每日活动量反馈给监督者，监督者根据受试者上一周的体力活动量，对每名受试者设定下周的目标体力活动量，要求每周活动量较上周增加20%，实验共为期12周。结果：与实验前比较，试验后后第1周、第4周、第8周和12周的步数、能量消耗和活跃时间均非常显著性的增加（P<0.01）；试验后各时间段步数均有所增加，其中，实验前工作日和休息日在17:30-20:00时间段步数最多，试验后工作日步数最多出现在20:00-22:00和17:30-20:002个时间段，休息日出现在8:30-12:00和20:00-22:002个时间段。结论：应用智能手机运动软件进行自我监控可以提高白领日常体力活动量，特别是交通和闲暇时间体力活动。目标设定、自我监控和表现反馈可能是体力活动干预中较为有效的行为改变技术（BCTs）。  相似文献   

Ferulic acid prevents liver injury and increases the anti-tumor effect of diosbulbin B in vivo   总被引：1，自引：0，他引：1  

Jun-ming WANG  Yu-chen SHENG  Li-li JI  Zheng-tao WANG 《Journal of Zhejiang University. Science. B》2014,15(6):540-547

The present study is designed to investigate the protection by ferulic acid against the hepatotoxicity induced by diosbulbin B and its possible mechanism, and further observe whether ferulic acid augments diosbulbin B-induced anti-tumor activity. The results show that ferulic acid decreases diosbulbin B-increased serum alanine transaminase/aspartate transaminase (ALT/AST) levels. Ferulic acid also decreases lipid peroxide (LPO) levels which are elevated in diosbulbin B-treated mice. Histological evaluation of the liver demonstrates hydropic degeneration in diosbulbin B-treated mice, while ferulic acid reverses this injury. Moreover, the activities of copper- and zinc-containing superoxide dismutase (CuZn-SOD) and catalase (CAT) are decreased in the livers of diosbulbin B-treated mice, while ferulic acid reverses these decreases. Further results demonstrate that the mRNA expressions of CuZn-SOD and CAT in diosbulbin B-treated mouse liver are significantly decreased, while ferulic acid prevents this decrease. In addition, ferulic acid also augments diosbulbin B-induced tumor growth inhibition compared with diosbulbin B alone. Taken together, the present study shows that ferulic acid prevents diosbulbin B-induced liver injury via ameliorating diosbulbin B-induced liver oxidative stress injury and augments diosbulbin B-induced anti-tumor activity.  相似文献
